I want to create a particle effects like Doctor Strange.
My implementation is create a particle emitter and emit particles to -Y direction. And then rotate it within a circle radius.
But I have some problems:
- The particles are not towards to the tangent of the circle path. Can I update the emit direction frequently ?
- When the emitter rotated, it seems the particles are rotated too ! How can the particles keeps the flying direction after emitted ?
- As the rotate speed grows up, the particles are no more rotate in an orbit of radius. Just launch my project.
